Explain how the theme of love is presented in Shakespeare's "Much Ado About Nothing"

This is an essay question that could come up in A Level based on the syllabus' I have looked at; there is not time or space to write out the full essay here, so I have gone for three key bullet points I would teach a student;Infidelity; infidelity is a constant presence in the play; it is through infidelity that the 'ado' occurs and many characters seem obsessed with the idea that a man cannot tell if his wife has been unfaithful, and it is a trap of this kind that breaks up Claudio and Hero. Though this naturally turns out to be a mistake; the connection between love and faithfulness is of great importance.Deception: Deception is essential to the ebb and flow of romance, Beatrice and Benedick get together because of it and Claudio and Hero are broken up by it; deception and trickery is used to expose true feelings throughout the play and it is only when tested by these artificial means that such things come to the fore.Love is funny: a source of much of the plays comedy is in the humour; the arguing between Benedick and Beatrice is funny because one understands that they are in love.Ultimately the play asks the question "Is love worth all this?" the title begs that question, I personally think Shakespeare answers "yes" but it is as all things in this discipline are; open to interpretation.
